Step-by-step process (detailed)

1. Preheat the oven

Preheat oven to 375°F (190°C) and lightly grease a baking dish.

2. Cook the meat

In a large skillet over medium heat, cook ground beef until browned, breaking it apart as it cooks. Drain excess fat if needed.

3. Add vegetables

Add chopped bell peppers and onion to the skillet. Cook for 4–5 minutes until softened, then stir in garlic and cook for another 30 seconds.

4. Add rice and liquids

Stir in uncooked rice, diced tomatoes, tomato sauce, and water or broth. Mix well to combine all ingredients evenly.

5. Season

Add Italian seasoning, salt, and black pepper. Stir to distribute the seasoning throughout the mixture.

6. Simmer briefly

Let the mixture simmer for 5 minutes, allowing the flavors to begin blending and the rice to absorb some liquid.

7. Transfer to baking dish

Pour the mixture into the prepared baking dish and spread evenly.

8. Cover and bake

Cover with foil and bake for 30–35 minutes, until the rice is tender and the liquid is absorbed.

9. Add cheese

Remove foil, sprinkle shredded cheese evenly over the top, and return to the oven.

10. Bake uncovered

Bake for an additional 10 minutes, until the cheese is melted and bubbly.

11. Rest and serve

Let the casserole rest for 5 minutes before serving to allow it to set properly.
